Also would make sense to enable this flag on:

Maybe we should mention which filters are lossy vs lossless. Removing unused resources is lossless for the most parts. |

@kellemNegasi can you update this and the other PR? A new release of unipdf has just been published so this should be ready once updated. |
Ok. I will do. |
@gunnsth I have tried to mention which filters are lossless on the README file. Can you check and see if I have to add or remove some filters to or from the list. |

Outdated

| From the available filters `CleanFonts`, `CleanUnusedResources`, `CombineDuplicateStreams`, `CombineDuplicateDirectObjects`,`CombineDuplicateDirectObjects`, `CleanFonts` and `CompressStreams` enable lossless compressions. |

UseObjectStreams also
CombineIdenticalIndirectObjects also
Actually most of them are lossless except ImageUpperPPI and ImageQuality.
